MUSIC-LEAF TURNER.

SPECIFICATION forming part of Letters Patent No. 244,281, dated July 12,1881.

Application filed April 18, 1881.

To all whom it may concern Beit known that I, IRA MOORE, a citizen ofthe United States, residing at Leavenworth, in the county of Leavenworthand State of Kansas, have invented certain new and useful Improvementsin Apparatus for Turning the Leaves of Music; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappcrtains to make and use the same, reference being had totheaccompanying drawings, and to thelet.- ters or figures of referencemarked thereon, which form a part of this specication.

My invention relates to an apparatus for turning the leaves of musicwhile the notes formed thereon are being played; and the object of myinvention is to provide certain novel devices for such purpose; second,to provide novel combinations of devices for producingtheresultshereinafterdescribed. Iaccomplish these objects by themechanism illustrated in the accompanying drawings, in which- Figure lis a perspective view, showing a plate of metal to which the other partsare secured, sliding bars having cogs upon portions of their uppersurfaces, guides for such bars provided with anti-friction rollers,oscillating arms having geared wheels or parts attached to them, andalso leafturners or clamps, handles for moving the sliding bars, andstrips of metal which constitute a rack for holding the sheets of musicbefore being placed in the leaf-turners. Fig.2 is a plan view, showingthe parts above enumerated; and Fig. 3 is a front elevation, partly insection, the leaf-turning arms and clamps being omitted for the purposeof showing the grooved anti-friction rollers.

Similar letters refer to similar parts in the several gures.

In constructingleaf-turners of this character I provide a plate ofmetal, A, or it may be of any other suitable substance that will supportthe other parts ot' the apparatus. This plate may be provided with holesfor the passage of screws for securing it to the instrument upon whichit is to be placed, and it is also provided with projecting studs orpins A A', for a purpose soon to be explained.

(No model.)

At or near the center horizontally, and near the lower ed ge ofthe plateA,there are secured two projecting ears or flanges, A2 A2, between whichthere are placed, and to which there are pivoted, two arms, B B, theoftice ot' which is to turn the leaves of sheet-music when said arms areproperly manipulated. The inner or pivoted ends of these levers areattached to geared pinions or wheels B2 B3 5 or, if preferred, cogs maybe formed upon the ends of the arms, an enlargement being formed thereonfor that purpose. These arms and their wheels are piv oted between theprojections A2 A2, secured to the plate A in such manner that theycanturn or oscillate freely, and yet be held in position by saidprojections.

To each of the arms or leaf-turners B and B' there is attixed a sliding`clamp, G, the lower end of which consists of a piece of metal having init a slot or groove for the passage of the arm, and upon one sidethereof' a spring for holding the clamp in its adjusted position on thearm.

For the purpose of holding the sheets to be turned in their properposition there is aiixed to the slotted portion of .the clamp a slottedstandard formed of wire or other suitable substance, between the twoarms of which the sheet to be turned is to be placed, so that as thepositions of the arms are changed the leaves will be turned and havetheir opposite sides presented to the performer.

For the purpose of moving the arms B B', as above described, there isprovided as many sliding bars D as there are arms, of which there may beany required number to enable the operator to turn as many sheets as maybe necessary to be used in playing one piece of music. These bars, neartheir inner ends, are provided, upon their upper surfaces, with cogs,which mesh into those formed upon the arms B and B', or the wheels towhich they are attached. The inner ends of the bars D pass between theprojections formed on plate A, their outer ends being held in positionby guides E E, which are secured to plate A, and carry at each of theirends anti-friction rollers E E', which bearupon the upper surfaces ofthe bars and keep them in position. The inner one of each of these pairsot' rollers has formed in its periphery a groove, in which the arms B Brest when in the positions shown in Figs. l and 2.

Attached to the outer ends of sliding bars D are pivoted handles D D',they heilig pivoted to said bars and provided with stops D2 D2, which,when the sliding bars have been moved far enough to cause the leaves tobe turned, come in contact with the studs A A of the plate A, and thusprevent said bars from bein g moved too far.

For the purpose of providing a suitable rest or rack for holding themusic upon the instrument when it is not desirable to place it in theturning-clamps, there is placed upon the plate A a shelf, and at itsends strips of metal, which project upward to or above the upper surfaceof the plate A, and thus hold the sheets in po. sition to be read andreadily turned by hand.

The operation of this apparatusis as follows: When it has been securedin its position on the musical instrument, the sheets to be turned A areplaced in the slotted portion of the clamps C C, the arms which carrythem having been previously turned so as all to pointin the samedirection when more than one sheet is to be turned, when, by applyingthe requisite force to the handles D D in succession, the arms orleaf-turners B B will be carried toward the opposite end of plate A, andthus the leaves will be successively turned as fast as the performerdesires, such turning being done by the person playing the instrument,0r by an attendant.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is

l. In an apparatus for turning the leaves of sheet-music, thecombination of the oscillating arms, each provided with an adjustablesliding clamp for holding the leaves to be turned, and sliding toothedbars for giving motion to the arms, with suitable mechanism foroperating them, substantially as set forth.

2. The combination ofthe plates A, the oscillatin g arms B B', thesliding` geared bars D D, the handles D D', guides E E, and stops D2 andA', the parts being arranged for joint operation substantially as setforth.

In testimony whereof I affix my signature in presence ot' two witnesses.

IRA MOORE.
